IMPROVEMENT IN TRACK-CLEARERS.

Specification forming part of Letters Patent No. 178,172, dated May 30, 1876; application filed April 1, 1876.

To all whom it may concern:

Be it known that I, JOHN MABBS, of Houghton, in the county of Houghton and State of Michigan, have invented a new and valuable Improvement in Railroad Snow-Removers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specificati'oi'i, and to the letters H and figures of reference marked thereon.

charge-pipe an air-forcing engine, which co1nmunicates with the scoop and discharge-pipe, for the purpose of forcibly ejecting the snow from the upper inclined portion of said pipe, as will be more fully understood from the following description In the annexed drawings, H represents part of a locomotive-engine of the well-known construction, and N designates a pilot attached .to the front part of thelocomotive in any suitable manner. F designates a, steam-engine, which receives steam from the steam-dome of the engine throughpipe G. D represents the case of an air-forcing engine, the wheels of which engine receive rotation from the pitman I) through the medium ofthe spur-wheels a a, and forcibly eject air through pipe E into the snow scoop or shoe A. This scoop or shoe is flattened laterally, and is somewhat wider than the width of the track. It is formed on the lower end of a discharge-pipe, which is composed of two sections, B G, and which has a diaphragm, P, dividing the lower portion of the scoop and discharge-pipe, as shown in Fig. 1. The capital letters I indicatetubes,

which are directed upward, and the capital letters M indicate tubes which are directed downward and outward from the shoe A. Tubes I spring from the diaphragm P,'and through them air from the engine D is forcibly ejected. The upper section of the discharge-pipe is arranged at an obtuse angle therewith, and is adjustable about the vertical axis thereof by means of spur-wheels K K, and a vertical shaft, L, on. which is a handwheel accessible to the engineer. By these means the inclined section 0 of the dischargepipe can be adjusted in any desired direction.

It will be seen from the above description that the snow which is picked up by the scoop A, will, by the strong blasts of air from the engine D, be forcibly discharged from the mouth of the section 0 far enough from the track to prevent drifts, the direction of the discharge being controlled by adjusting. said section. It will also be seen that the air ejected from tubes M will clear the track from any snowwhich will not be taken up by the scoop.

What I claim as new, and desire to secure by Letters Patent, is

l. The pipe B, provided with the shoe A, and diaphragm P, with a series of openings, I I, substantially as and for the purpose set forth.

2. The shoe A, having diaphragm P, with openings I and openings M in its bottom, substantially as and for the purpose set forth.

'3. The combination, with the pipe 13, having a shoe, A, with openings M in its bottom, and a diaphragm, P, with a series of openings, I, of an air-forcing engine, D, and connectingpipe E, substantiallyas and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN MABBS.
